IMPROVEMENT In HAND-ENGINE.

TOALL wHoM IT MAYcONcERrnf y t f i Beit known that we, CHARLES T.ULMAN,.of the city of New York, county of New York, and in the Stateof'NewYork, and MARCUS Bochum, of the city of Brooklyn, countyrif-Kings, and in the State of lNew York, have invented a newanduseful'Impx-ovement inHaud-Engnes; and we do hereby declarethe following.tobe

a full., clear, and exact deseription of the same, reference being .hadto the accompanying drawings, (three l,

sheets,) making apart of this specification,` in whichp Figurel isl aside elevation. l

filiali theligures in the drawings the letters of reference' employeddenote identical parts. Our inventioneonsists ofthe c onstruction of ahand-engine worked by means of levers, arranged in such a mannery thatbut little force is required to start and to keep the enginesworking.parts going.

A v To enable others skilled in the art to make and use our invention,wewill proceed to describe its construction and operation. A v l p VOurhand-engine consists of two vertical rectangular frames orl standards A,supporting the machinery, and placed far enough from each other toallowthe Imachinery to work.- Each frame, A, consists of two parts, a lowerand an upper one, well secured toeach other. The lower frames, A,incline towards each other st their upper parts,1spreading outat thebase in order to 'give a stronger rest for the upper frames A.' Bothframes are placed in a parallel .position towards each other, and wellsecuredto each other with braces, &c. B is a triangular peceand used asa. crank or quarter crook/At its lower points C itlis 'attached to armsC, as shown. in figs. 1, 2, 4, and I The shai't N, which4 rests inbearing'N on the upper part ofthe lower frames A Aforming a right anglewith the frames, projects over both frames,`. and at each of its endssupports a wheel, M, which may be used as a ily-wheel. At each end, andbetweenV the lower frames, a meinA` lever, E, is Vhung -on a bolt orpivot, E, by

4means of arms D and C.1 The lever E is connected with thecrank ZB.

When the machine is not worked, the main leverE will't occupy a verticalposition, as shown in iig, 1, and lig. 2 shows Vthe lever E in aninclined position At'its lower endfthe lever' E is provided with alprojection,

forminga right angle with the 'shaft of the lever E. The size of, thisprojection or weight will "determine the power. By increasing ordecreasing thesize or weight of said4 projection the power willbeincreased or decreased. The main lever Eis at-its upper part, a littlebelow the pivot'EQ-provided with ajont, E', which might be useful incase the engine were placedon any swimming-surface'. The joint or hingeE, shown in iig. 3, will Vallow the lower part of the leverV to swingsideways, and'in such .case the frames A mustbe put far enough'from eachother, and so constructed thatthey do not interfere with the motions ofthe lever E. In gs. 2 and 3 another shape of lever E is shown than infig-1.

Thelever E is actuated by arms L L, which are pivoted at E" to minorarms E E', securedto the upper part of levers E E. The connectng-rods orarms L arc atl their upperends provided -withslots L' L', in which lebelt or pin, I, moves; the bolt I resting in socket. E, which is `irmlyattached to the lower point of a frame or workingbeem, G. This frame isconstructed like a'rhomboid; its sides are curved outwards, and proyidedp withl slots G Gr'. The working-beam G is at its upper point pivoted tothe vertical upper frames A A', where it hangs suspended, and allowed tooscillate when worked upon by levers H.

i 4The handles K, by whichv the engine is worked, are pivoted to theupper part of the vertical frames A A' at K', and at their upper partsprovided with arm I,as shown in fig. 1. This erm I projects towards theinner p pnrtlof the machine, and has points `I', which work in slots H".

H H are levers of a triangular form, pivoted near each other in theupper part of the vertical frames A',

a little below the pivots K. Friction-rollers lI" and H are secured inarm I, insuch a manner that it touches the upper face of lever H andframe G. At' their lower ends the levers H are provided with arectangular projection, in which a pin, H', is inserted, and said pinslH working inslots G.

. `When-the arms K are moved up and down', the machinery is put inmotion, the movements of the arms K will communicate an oscillatingmotion to the levers lH, and the motion through pins H working in slotsG',

will actuate upon the working-beam G. Arms L- connected through thesocket F will, when said socket com mences to oscillate, also he put inmotion, and thereby working the main levers-E. Thus worked upon, thelevers E will, through the agency of arms D and Crevolve the crank B,andthe axle und ily-wheel M thereby put in motion. K

We do not confine ourselves to the precsemode of construction ofourimprovement, nor the particular use; but *A I What we claim, and desireto secure by Letters Pstent, is 1. The combination of handles K,projections I, levers'H, working-beam G, socket E, and arms L, whenarranged as and for the purpose set forth. Y l i l 2. The main lever E,when constructed as and for the purpose set forth. l 3. The combinationof arms D and C; and the ltriangular,crank or quarter-crook B, whenarranged as and for the purpose set forth.
